Feedback: Mana drain mob aura

The Mana Drain mob aura is so huge it feels awful!
Also, it is very difficult to see the outer half of it, especially on complex terrain.

Can't find a way to counter it right now - i've encountered two enemies like that and both were incredibly fast, always aggresively pushing in, with no way to not only attack but even (duh) get away. First one I was able to outrun by baiting an attack and running, but the second one (some large fly in Act 2) - it just stays glued to you.
